It has a well-defined eye and everything. See discussion and images from central Pacific Hurricane Center at http://www.prh.noaa.gov/hnl/cphc/. I'm not sure how common this type of thing is.Davidhttps://www.blogger.com/profile/02814313368731066590noreply@blogger.comtag:blogger.com,1999:blog-6168620747792092240.post-60063962060608812462010-12-17T22:06:28.822-07:002010-12-17T22:06:28.822-07:00Thanks for the references.

I noticed that this one has developed a lot of deep convection right around the center (http://aviationweather.gov/data/obs/sat/intl/ir_ICAO-M_bw.jpg and http://www.weather.unisys.com/satellite/sat_ir_west_loop-12.html) which suggests it might be developing some warm-core characteristics. I think the GFS analysis hints at this also. The ocean temperature there is in the mid to upper 70s F (http://www.ssec.wisc.edu/data/sst/latest_sst.gif).Davidhttps://www.blogger.com/profile/02814313368731066590noreply@blogger.comtag:blogger.com,1999:blog-6168620747792092240.post-40355515070370472102010-12-17T13:35:29.477-07:002010-12-17T13:35:29.477-07:00I believe this is an example of a Kona Low.

Looks like it gradually migrates to the northwest and eventually gets absorbed into a large trough in the western Pacific about a week from now. At any rate, it sure has a nice tropical tap into the ITCZ. These sutropical systems are very interesting to me... they are clearly cold-core systems but distinctly different from the mid-latitude type.Davidhttps://www.blogger.com/profile/02814313368731066590noreply@blogger.com
